Abstract

　本発明は、磁束密度の高調波成分を低減する界磁子である。回転軸（Ｐ）に平行な方向で永久磁石（２０）は第１の磁性板（１，３）と接している。第１の磁性板（１）は第１及び第２の磁性体（１０，１２）と、第１及び第２の非磁性体（１１，１３）とを備えている。第１の磁性体（１０）は極中心を含んで一の永久磁石と回転軸方向で接している。第１の磁性体（１０），第１の非磁性体（１１）、第２の磁性体（１２）、第２の非磁性体（１３）は、極中心を始点として回転軸を中心とした周方向においてこの順に配置されている。極中心側の第２の非磁性体（１３）の端部（１３１）が極間からなす角度θ１は、極対数をＰｎ、３以上の奇数をｉとしたとき、０＜θ１＜１８０／（ｉ・Ｐｎ）である。極中心側の第１の非磁性体（１１）の端部（１１１）が極間からなす角度θ２は１８０／（ｉ・Ｐｎ）≦θ２≦１８０・２／（ｉ・Ｐｎ）である。
